Someone pointed me in the right direction on the old site when I had the same trouble.
Mine was on the side of the fan housing under the dash and was easy to get out, just 2 screws I think. I didn't replace the whole assembly but got a replacement resistor from a TV repair shop for £2 and soldered it in myself
